Abstract
Purpose The objective of this study was to evaluate the therapeutic efficacy of the curcumin analogue L6H4 in attenuating liver fibrosis and alleviating insulin resistance in streptozotocin-induced diabetic rats. Methods Male Sprague-Dawley rats were fed a high-fat diet to induce insulin resistance, followed by streptozotocin injection to induce diabetes. The rats were then treated with L6H4 for eight weeks. Body weight, metabolic parameters, liver function, and liver histopathology were evaluated. Immunohistochemistry was performed to assess the expression of TGF-β1, TIMP-2, and MMP-2 in liver tissues. Statistical analysis was conducted using one-way ANOVA and Spearman rank correlation test. Results L6H4 treatment effectively reversed the weight gain associated with a high-fat diet and improved metabolic parameters in diabetic rats. Liver function markers, such as ALT and AST, were reduced after L6H4 treatment. Histological analysis showed improved liver morphology and reduced fibrosis in L6H4-treated rats. Electron microscopy revealed improved ultrastructural features of hepatocytes. Immunohistochemistry demonstrated downregulation of TGF-β1 and TIMP-2 expression and restoration of MMP-2 expression in the liver tissue of L6H4-treated rats. Correlation analysis showed a significant positive correlation between TGF-β1 and TIMP-2 expression. Conclusion The findings suggest that L6H4 has therapeutic potential in attenuating liver fibrosis and alleviating insulin resistance in streptozotocin-induced diabetic rats. The hepatoprotective effect of L6H4 may be attributed to its anti-inflammatory properties and its ability to target molecules involved in fibrosis. Further research is warranted to explore the potential of L6H4 as a treatment option for nonalcoholic fatty liver disease and type 2 diabetes.

Abstract
OBJECTIVE To analyze the clinical value of combined detection of serum APE1-Aabs and CEACAM-1 in pathological diagnosis of colorectal cancer. PATIENTS AND METHODS From December 2014 to July 2016, 60 patients with colorectal cancer and 50 healthy subjects were enrolled in this study. The levels of APE1-AAbs, CEACAM-1 and CEA in the serum were measured, and the clinical value of each index in the diagnosis of colorectal cancer was analyzed. RESULTS The level of serum APE1-AAbs in colorectal cancer group was significantly higher than that in healthy control group (p < 0.05). The levels of serum CEACAM-1 and CEA in colorectal cancer patients were significantly higher than those in healthy control group (p < 0.05). The sensitivity and accuracy of APE1-AAbs and CEACAM-1 in the diagnosis of colorectal cancer were significantly higher than separate detection of APE1-AAbs, CEACAM-1 or CEA. CONCLUSIONS Combined detection of serum APE1-AAbs and CEACAM-1 has the advantages of high sensitivity and good accuracy in the diagnosis of colorectal cancer, and it is worthy to be popularized in clinical practice.

Abstract
Background The methods routinely used to detect trichomonads in the lungs are not sensitive enough, and an effective method is urgently needed. Method Primers were first designed to match the conserved area of the 18S rRNA gene of trichomonads. Then, nested PCR was carried out to detect trichomonads in bronchoalveolar lavage fluid (BALF). Finally, all positive specimens were subjected to DNA sequencing and phylogenetic analysis. Results Among 115 bronchoalveolar lavage fluid samples, ten samples tested positive in nested PCR (10/115), while no samples were positive in wet mount microscopy (0/115) (P < 0.01). Among the ten positive specimens, two were identified as Tetratrichomonas spp. and the other eight as Trichomonas tenax in phylogenetic analysis. Conclusions Nested PCR is an effective way to detect trichomonads in bronchoalveolar lavage fluid.

Abstract
Our previous long noncoding RNA (lncRNA) microarray revealed that lncRNA-TCONS_00026907 is aberrantly expressed between cervical cancer tissues and adjacent tissues. This study aims to explore the potential role of TCONS_00026907 in the development of cervical cancer. The expression levels of TCONS_00026907 in cervical cancer tissues and adjacent tissues from 83 patients of cervical cancer were detected by quantitative real-time polymerase chain reaction and the survival rate was analyzed. In vitro, HeLa and SiHa cells were transfected with small hairpin RNA (shRNA)-TCONS_00026907, then cell proliferation, cycle distribution, apoptosis, migration and invasion were measured. To confirm TCONS_00026907 regulates expression of ELK1 through inhibiting miR-143-5p, overexpression of miR-143-5p and silencing of ELK1 were, respectively, performed in HeLa and SiHa cells. Results showed that TCONS_00026907 level was significantly higher in cervical cancer tissues compared to noncancerous tissues and the survival rate was lower in the high expression group. Silencing of TCONS_00026907, overexpression of miR-143-5p and silencing of ELK1 inhibited cervical cell cycle, proliferation, migration, and invasion, but promoted apoptosis, respectively. Furthermore, silencing of TCONS_00026907 suppressed the growth of cervical tumors and altered the expression of ELK1, p-ELK1, C-fos, Cyclin D1 and Bcl-2 in vivo. Our study identifies TCONS_00026907 as a potent proto-oncogene and indicates that TCONS_00026907/miR143-5p/ELK1 regulatory pathway plays an important role in cervical cancer.

Abstract
To validate its efficacy in the context of the human immune system, a novel therapeutic vaccine of hGM-CSF/hTNFα surface-modified PC-3 cells against human prostate cancer was evaluated in the human peripheral blood lymphocytes-severe combined immunodeficiency (huPBL-SCID) chimeric mouse model. The hGM-CSF or/and hTNFα modified vaccines inhibited prostate cancer growth effectively so as to prolong the mouse survival significantly. The splenocytes from the hGM-CSF/hTNFα vaccine-inoculated mice showed the strongest tumor-specific cytotoxicity against PC-3 cells and the highest production of IFNɤ. These features indicated that type 1 protective immune response was induced efficiently against human prostate cancer and further enhanced through synergetic adjuvant effects of hGM-CSF and hTNFα.

Abstract
Cat eye syndrome (CES) is a developmental disorder with multiple organ involvement, associated with the duplication of a 2-Mb region of 22q11.2. Using exon trapping and genomic sequence analysis, we have isolated and characterized a gene, CECR1, that maps to this critical region. The protein encoded by CECR1 is similar to previously identified novel growth factors: IDGF from Sarcophaga peregrina (flesh fly) and MDGF from Aplysia californica (sea hare). The CECR1 gene is alternatively spliced and expressed in numerous tissues, with most abundant expression in human adult heart, lung, lymphoblasts, and placenta as well as fetal lung, liver, and kidney. In situ hybridization of a human embryo shows specific expression in the outflow tract and atrium of the developing heart, the VII/VIII cranial nerve ganglion, and the notochord. The location of this gene in the CES critical region and its embryonic expression suggest that the overexpression of CECR1 may be responsible for at least some features of CES, particularly the heart defects.

Abstract
Sweeping-field electrophoresis is investigated as a method for increasing the resolution of low-voltage slab gel separations. In this technique a low direct current (DC) voltage is time multiplexed to an array of periodically spaced electrodes placed along the length of the slab in a manner that follows the band migration. Because the electrode spacing is smaller than the slab length, a larger field is generated, yielding an improved separation. The effect of the nonuniform electric field on band distortion is studied in some detail. Experimental band distortion results showed good agreement with theoretical predictions in a macroscopic sweeping-field electrophoresis system. Both analytical and numerical results show that band distortion can be effectively minimized when an appropriate sweep rate is selected for a narrow band range. Using this scheme we have achieved the same number of theoretical plates as a DC-driven system with one third of the drive voltage.
